Korea Health Insurance for Foreigners: How to Enroll & Use It
If you are moving to South Korea for work, study, or a long-term stay, one of the first practical questions you may have is: Do foreigners need health insurance in Korea?
In many cases, yes. Foreign employees working at an eligible workplace are generally enrolled in Korea's National Health Insurance (NHI) through their employer. Many other registered foreign residents become subject to National Health Insurance after living in Korea for six months, although the starting date can be different for certain visa types, including students and some other residents.
Once you are covered, you can use Korea's National Health Insurance at hospitals, local clinics, pharmacies, and for many medical tests and treatments. However, insurance does not mean that medical care is completely free. You normally pay part of the cost yourself.
If you live in Korea long term, check your health insurance status soon after receiving your Residence Card. Employees are usually enrolled through their workplace, while many non-employed foreign residents are enrolled under the self-employed system after meeting the residence requirements.
1. Do Foreigners Need Health Insurance in Korea?
Korea operates a public health insurance system through the National Health Insurance Service, or NHIS (국민건강보험공단).
For foreigners, the rules depend mainly on your employment status, visa, residence period, and family situation.
If you work for a Korean employer
Foreign employees who work at workplaces covered by National Health Insurance are generally enrolled as employee-insured members.
Your employer normally handles the enrollment process, so you usually do not need to visit an NHIS office just to sign up.
You will normally see health insurance contributions deducted from your monthly salary.
If you are not covered through an employer
Many registered foreign residents who remain in Korea for more than six months are required to join National Health Insurance as self-employed insured members.
Eligible residence statuses include many D, E, F, G and H visa categories, but the exact starting date is not identical for every visa.
For example, international students and certain residents may have special eligibility rules. Because immigration status can change, it is safer to check your exact visa with NHIS rather than assuming that the six-month rule always applies in exactly the same way.
What about short-term tourists?
If you are visiting Korea for a normal short holiday, you should not assume that Korea's National Health Insurance will cover you.
Short-term visitors should consider travel medical insurance that covers:
- outpatient treatment
- emergency-room visits
- hospitalization
- prescription medicine
- medical evacuation or repatriation
Medical treatment is widely available in Korea, but an uninsured visitor may have to pay the full medical bill.
2. How to Enroll in Korean Health Insurance
The enrollment process is easier once you know which category you belong to.
Option 1: Employee insurance
If you are working for a company covered by National Health Insurance, your workplace usually reports your eligibility to NHIS.
A typical foreign employee therefore does not personally buy National Health Insurance in the way someone might purchase private insurance.
A simple example:
- You arrive in Korea with an E-7 work visa.
- You register your residence and receive your Residence Card.
- You start working for a company covered by NHIS.
- Your employer registers you for employee health insurance.
- Your share of the contribution appears on your monthly payslip.
If you start a new job and do not see any health insurance deduction after your enrollment should have started, ask your employer's HR or payroll team first.
Option 2: Self-employed insurance
Foreign residents who are not employee-insured may become self-employed members after meeting the applicable residence and visa requirements.
In many cases, NHIS receives immigration and residence information automatically. However, you should contact NHIS if you believe you should be enrolled but have not received an eligibility notice or contribution bill.
Can a spouse or child be registered as a dependent?
Possibly, but dependent status is not automatic simply because two people are married.
A dependent generally needs to meet NHIS requirements involving:
- family relationship
- income
- property
- residence status
- period of residence in Korea where applicable
NHIS may ask foreign applicants for documents proving a marriage or family relationship. Documents issued overseas may require authentication, such as an Apostille or other official confirmation, and Korean translation requirements may also apply.
Foreign dependents can also be subject to residence-period rules, with exceptions applying in certain situations. This is one area where it is worth checking directly with NHIS before preparing documents.
Documents worth keeping ready
Depending on your situation, useful documents may include:
- Residence Card, formerly commonly called an ARC
- passport
- employment information
- marriage certificate
- birth certificate for children
- proof of family relationship
- Apostille or other authentication where required
- Korean translation of overseas documents when requested
Do not prepare expensive notarized documents before checking exactly what NHIS requires for your case.
3. How Much Is Health Insurance in Korea for Foreigners?
There is no single monthly National Health Insurance price that applies to every foreign resident.
Your contribution depends on whether you are an employee-insured member or a self-employed member.
Employees
For 2026, the employee National Health Insurance contribution rate is 7.19% of the applicable monthly wage.
For a standard employee, the contribution is generally shared:
- Employee: 50%
- Employer: 50%
This means the employee's health insurance portion is approximately half of the total health insurance contribution calculated from the applicable wage.
For example, imagine your applicable monthly salary were KRW 3,000,000.
The basic calculation would be:
- KRW 3,000,000 × 7.19% = KRW 215,700 total health insurance contribution
- Employee's 50% share = approximately KRW 107,850
- Employer pays the remaining 50%
This is only a simplified example. Your actual payroll deduction may be different because the official wage base and other social-insurance charges can affect what appears on your payslip.
Self-employed foreign residents
The calculation is different if you are registered as self-employed insured.
NHIS assesses contributions using the rules applicable to the self-employed system and information such as income and property.
For some foreign self-employed members, special contribution rules or minimum contribution requirements may apply.
Because of this, you should not rely on an old blog post that says every foreigner pays exactly the same monthly amount.
The safest figure is the amount shown on your current NHIS bill.
International students
Eligible international students, including certain D-2 and D-4 visa holders, may qualify for a reduced contribution under NHIS rules.
The NHIS English guidance currently states a 50% contribution reduction for qualifying student categories under the applicable conditions.
However, your visa, residence situation, household status, and eligibility can affect the final amount, so check your bill rather than calculating your payment solely from the reduction percentage.
4. How to Use Korean Health Insurance at a Hospital
Using National Health Insurance in Korea is usually straightforward once your eligibility is active.
Step 1: Choose a clinic or hospital
For common problems such as a cold, stomach pain, a skin problem, mild back pain, or an ear infection, most residents start with a local clinic.
You may see signs such as:
- 내과 — internal medicine
- 이비인후과 — ENT / ear, nose and throat
- 피부과 — dermatology
- 정형외과 — orthopedics
- 안과 — ophthalmology
- 산부인과 — obstetrics and gynecology
- 소아청소년과 — pediatrics
Local clinics are often cheaper and faster than going directly to a large university hospital.
Step 2: Bring identification
Korean medical institutions have strengthened patient identity verification.
Foreign residents should therefore bring an accepted photo ID, such as their Residence Card. A passport may also be accepted for identity verification in applicable situations.
It is a good habit to keep your Residence Card with you when visiting a clinic or hospital.
Step 3: Register at reception
At the reception desk, you can say:
“I have Korean National Health Insurance.”
If your eligibility is active, the hospital can normally process the insured portion of covered treatment.
You pay only your required patient share plus any services that are not covered by insurance.
Step 4: Get your prescription
In Korea, doctors commonly give you a prescription after the consultation.
You then take it to a pharmacy, called a yakguk (약국).
The pharmacy is often located near the clinic or in the same building.
National Health Insurance usually applies separately to eligible prescription medicines, and you pay the applicable pharmacy co-payment.
How much do patients pay?
Your out-of-pocket cost depends on the type of hospital and treatment.
Under the general NHIS co-payment structure:
- inpatient treatment is generally subject to a patient share
- clinic outpatient visits normally have a lower co-payment than larger hospitals
- general hospitals usually have higher outpatient co-payments
- tertiary hospitals can have substantially higher outpatient co-payments
- pharmacy prescriptions also require a patient co-payment
For many insured services, NHIS lists the general inpatient co-payment as 20% of covered treatment costs, although reduced rates apply to certain registered serious diseases.
For ordinary outpatient treatment, your percentage varies depending on the level and location of the healthcare institution.
Do I need a referral for a major hospital?
Korea has a healthcare delivery system designed to encourage patients to use clinics and smaller hospitals before tertiary hospitals.
For treatment at a major tertiary hospital, a referral may be required for normal insurance benefits in many situations.
If your condition is not an emergency, beginning at a neighborhood clinic is often the simplest and least expensive approach.
5. Important Tips for Foreign Residents
Keep your address updated
NHIS eligibility and contribution notices are linked to your registered residence information.
If you move, make sure your immigration and residence records are updated properly. Missing an insurance bill because it went to an old address can create unnecessary problems.
Do not ignore NHIS bills
If you are responsible for paying your own contribution, treat the monthly bill like any other important public payment.
Failure to pay health insurance contributions can result in collection action and may affect your ability to receive normal insurance benefits in certain circumstances.
If the amount looks wrong, contact NHIS rather than simply ignoring the bill.
Private insurance and NHIS are not the same thing
Some foreigners arrive in Korea with private insurance from their home country.
Having private insurance does not automatically mean that you are exempt from Korean National Health Insurance.
In certain cases, a foreign employee with equivalent medical coverage under foreign law, overseas insurance, or an employer contract may be able to apply for exclusion from Korean employee insurance.
This requires formal proof and approval. Do not stop paying NHIS simply because you also have private insurance.
Use the foreign-language NHIS help line
If your case involves visa changes, dependents, overseas documents, contribution reductions, or an unexpected insurance bill, contacting NHIS directly is usually faster than relying on online forums.
NHIS main number: 1577-1000
Foreign-language consultation: 033-811-2000
NHIS also operates centers that handle health insurance matters for foreign residents.
Health insurance can also cover preventive care
National Health Insurance is not only for treatment after you become sick.
Eligible insured residents may also qualify for national health checkups and certain cancer-screening programs depending on age and other criteria.
General health checkups covered under the NHIS program can be available without a patient charge for eligible people.
Conclusion
Understanding Korean health insurance is an important part of living in South Korea as a foreign resident.
If you work for a Korean employer, your company will usually handle your National Health Insurance enrollment and share the contribution with you. If you are studying, looking for work, running a business, or living in Korea without employee coverage, your eligibility depends more heavily on your visa and residence status.
The most important things to remember are simple:
- Check your NHIS eligibility after settling in Korea.
- Do not assume every foreigner follows exactly the same six-month rule.
- Check your monthly contribution notice carefully.
- Bring your Residence Card or other accepted ID when receiving medical treatment.
- Start with a local clinic for ordinary health problems when appropriate.
- Ask whether expensive treatments are covered or non-covered before agreeing to them.
- Contact NHIS directly if your visa, employment, address, or family situation changes.
For short-term visitors, National Health Insurance should not replace travel insurance. For long-term residents, however, Korea's National Health Insurance can make routine medical care, hospital treatment, prescriptions, and preventive healthcare much more manageable.
